Ranbir hails singers, says they contribute a lot in actor's life

"Kishore Kumar has sung for my father so many times. While doing 'Bachna Ae Haseeno', I got an opportunity to sing a few lines of his (Kishore Kumar) song too. A singer contributes a lot in an actor's life and must be given credit for that," he told reporters Monday at a press conference here arranged for Colors Screen Awards.

Being a huge fan of the singer, Ranbir, 30, said: "Whenever we talk of Kishore Kumar, all we can say is that he used to sing from his heart."

The actor also revealed that the script of the film is not ready at the moment.

"It is a great opportunity for me to act in a biopic of Kishore Kumar on screen. The script is not ready at the moment and we are waiting for Anurag Basu to complete it. It is my duty as an actor that I do full justice to it," said Ranbir who proved his versatility with films like "Rockstar" and "Barfi".

Ranbir will not be singing in the film, but "I will try my best to look and act like him".

At the moment, the actor is busy with two of his upcoming films - "Yeh Jawaani Hai Deewani" and "Besharam".
